VA Disability: Migraines

Reviewed by Jonathan Teplitsky · Updated June 2026

How does the VA rate migraines?

The VA rates migraine and headache disorders under 38 CFR § 4.124a, Diagnostic Code 8100. There are only four levels — 0%, 10%, 30%, and 50% — and 50% is the highest schedular rating available for migraines. There is no 60%, 70%, or 100% box on the migraine schedule. The percentage you receive depends almost entirely on one thing: how often you suffer characteristic prostrating attacks.

You can read the neurological rating schedule yourself at the 38 CFR Part 4 source.

What "prostrating" really means — the linchpin word

Here is the single most misunderstood point in migraine claims: a migraine that merely hurts is not enough. The rating criteria do not count headaches — they count prostrating attacks. A prostrating attack is one so severe that you have to stop what you are doing and lie down until it passes. You are incapacitated, not just uncomfortable.

Most denials and low ratings turn on this word. A veteran may have frequent, painful migraines and still be rated 0% because nothing in the record describes the attacks as prostrating. When you talk to your doctor or the examiner, describe what the migraine forces you to do: drawing the blinds, lying down, leaving work, being unable to function. Make sure the words "prostrating" — or a plain description of having to stop and lie down — actually appear in your medical notes.

The 50% rating and "severe economic inadaptability"

The 50% level is the top of the migraine schedule, and it has a second term that trips veterans up: severe economic inadaptability. To reach 50% you need very frequent, completely prostrating, and prolonged attacks that are productive of severe economic inadaptability — in plain terms, migraines that substantially harm your ability to hold or perform a job.

Two things matter here. First, the VA does not require you to be totally unemployable to get 50% — the attacks only need to be capable of producing severe economic inadaptability, which the courts have read as substantial work interference rather than total job loss. Second, because 50% is the schedular ceiling, a veteran whose migraines genuinely prevent steady work is not stuck there. Through TDIU (Total Disability based on Individual Unemployability), you can be paid at the 100% rate even though your migraine rating maxes at 50%, if the migraines prevent substantially gainful employment.

Migraines secondary to PTSD, TBI, or your neck

Migraines rarely appear out of nowhere. They are frequently granted secondary to another service-connected condition, which means the cause traces back to a disability the VA already recognizes:

• PTSD — chronic stress, sleep disruption, and the medications used to treat it are recognized migraine triggers. See our PTSD VA rating guide.
• Traumatic brain injury (TBI) — post-traumatic headaches are one of the most common residuals of a head injury. See TBI VA rating.
• Neck (cervical) conditions — cervicogenic headaches stemming from a service-connected neck injury are commonly claimed as secondary migraines.
• Medications — drugs prescribed for another service-connected condition can themselves cause chronic headaches.

For any of these, a medical nexus letter linking the migraines to the underlying service-connected condition is the piece of evidence that wins the claim.

The headache diary and the C&P exam

The most useful evidence in a migraine claim is something you create yourself: a headache diary. For each attack, record the date, how long it lasted, how severe it was, and — most important — whether you had to stop activity and lie down. A diary that shows, for example, one prostrating attack a month over six months is exactly what the 30% criterion asks for. Frequency and prostration are what move you between the 10%, 30%, and 50% levels, and a contemporaneous log is far more persuasive than memory.

Bring that diary to your C&P exam. Because migraines are invisible and often gone by the time you sit down with an examiner, the exam relies heavily on your history and your records. Describe the attacks in functional terms — how often they force you to leave work, lie down in the dark, or cancel plans — and make sure the examiner understands the attacks are prostrating, not just painful. Buddy statements from a spouse or coworker who has seen you incapacitated can corroborate what the examiner cannot observe in one visit.

Estimate your combined rating

Migraines are rarely your only rated condition — they often ride alongside PTSD, TBI, or a neck disability. If you carry several ratings, use our VA disability rating calculator to see how they combine. VA math is not simple addition, and a 50% migraine rating stacked with other conditions can move your combined percentage well beyond 50.
